Senior🎓
Top SchoolDenys Serhiienko is a Senior Web Developer with 12 years of experience building backend systems and APIs, currently delivering solutions at SoftServe from Ukraine. He has a strong PHP and web-services background shaped by work on bank-grade secure systems and earlier leadership of a small CRM team where he architected core modules. Comfortable with remote work, he prefers a hybrid schedule with minimal office time and excels at debugging under constrained data conditions—a skill he jokingly calls "telepathy." His master's in Computer Systems and Networks underpins pragmatic architecture choices and reliable system design. Colleagues know him for turning messy legacy tasks into stable, maintainable services while balancing hands-on coding with mentoring.
